Yes, ladies and gentlemen, a Twitter war has broken out between Floyd and Fitty, with the first battle being waged on Friday night. And it started with 50 Cent throwing the first jab, letting Mayweather know that undefeated Yuriorkis Gamboa, his fighter, will move up in weight to challenge Mayweather.

50 Cent tweet: "GAMBOA WANTS TO FIGHT FLOYD. I will put up a extra 20 million for the winner. He don't like it that Floyd pulled out. #SMSAUDIO"
